This device is used to give good leverage for turning small difficult items eg. gas or radiator taps. The head has a bed of sprung stainless steel rods, which when pressed around an object, retract, conform around its shape, and provide a purchase around it when the handle is turned. The handle is a black plastic T-piece, which is easy to grip. It is small enough to be carried around in a pocket or hand bag.
Head size 95mm (33/4″) wide. 50mm (2″) deep. Weight 130g.
